Exam

Unfortunately, the network burped on me as I was saving exam questions for the final. As a result, there are only 84 points on it, and none of the chapter 24 questions I wanted to assign for bonus. However, the questions that are in there are comprehensive, other than Ch. 24. Therefore,

1. I will scale the 84 points up to 100 points, and give everyone the benefit of rounding UP to the nearest whole number score, and
2. I will figure out another method for scoring bonus points from the chapter 24 mini-quiz.

So do your best on a slightly shorter exam than I had planned, and I will square everybody away grade-wise on this exam.

Summary analytic test in Webcourses

In another Webcourses area, "GEP PSC1121 11Spring", there is a summary analytical test you should all take this week, before hitting the final exam. It is not part of your semester grade but part of the university's assessment plan for its GEP program. It takes about 15 minutes or less.

Final Exam Week Bonus Learning Module

Tomorrow begins exam week. Therefore I am releasing a learning module featuring Ch. 24 concepts that will lead to bonus point question on the final exam this coming Saturday.

By the way, you have only 4 attempts on this mini-quiz, so make them count!
